    • Great bike!
Color: Matte Blue Size: 24 Inch
Well made and happy with purchase. Bike did ship with some paint chips and a few scratches but I figured my 9yo would do worse. Purchased in November 2025 and still growing strong end of April 2026. It’s used daily. Would recommend. The disc brakes are fantastic!! Purchased the 24” for 9yo boy.

I bought this bike because it was the cheapest disc brake mountain bike that was a 24". All the clamp brake bikes have a flimsy bracket that bends pretty easily. I felt it was worth upgrading the brakes and this bike seems to work. It came in early and was easy enough to assembly. The front disc brake does have a small wobble in it when spinning but it does not seem to effect the braking. It does not rub when spinning after adjusting the front wheel a bit. They have several video guides that were helpful but I would not expect any other support. The bike is made in China but I did not see any defects. The packaging was good and the tires seem good. ... show more

    • Good bike for the price
Color: Blue Size: 27.5 Inch
The assembly was surprisingly easy, took me like 20 minutes. The frame is solid, and the shifter, gears, and cables all work just fine. It looks really nice too. It's a good size for a teen. It's not for rough trail riding or dirt jumping but if you are looking for a basic mountain bike for an affordable price, this one exceeded expectations. ... show more

Package arrive on time. Everything was good when I took it out of the box. It took me 20 minutes to build the bike which was easy for me cause I watched the video. I’ve driven the bike for a week now and I love it!

    • Tuning front shifter very difficult.
Color: Yellow Size: 27.5 Inch
Front shifter adjustment very difficult. I still haven't got it. I go back and forth. Lget low and middle then just th e outside 2 then 3 but the down shift skips the middle but shifts up again. It is light and brakes work good. I have had no problem with 4 previous bikes.

Color: Blue Size: 27.5 Inch
Great bike for the price! Easy to assemble. Bought this for my man for Valentines Day. I bought the Black matte with blue lettering and 27.5 inch tires. Good for a man to ride. We are very active and this is another thing to do! Go bike riding!
